Definitions
- the invention relates to a dual-mass flywheel, in particular for the drive train of a motor vehicle according to the preamble of patent claim 1.
- a dual mass flywheel (DMF) in the drive train of a motor vehicle has the task of damping torsional vibrations of the engine and not transmitting it to the transmission.
- the dual-mass flywheel has a primary mass that can be attached to the crankshaft of the internal combustion engine and a secondary mass that is rotatable relative to the primary mass about the axis of rotation.
- the primary mass and secondary mass are connected to one another in a torsionally elastic manner via a torsion damper device.
- the damping is achieved by relatively high mass inertias of the primary and secondary masses.
- the secondary mass is e.g. connected to the clutch by means of a drive plate connected via splines.
- DE 43 39 421 A1 describes a dual-mass flywheel with a primary sheet metal part which can be fastened centrally to the axis of rotation of a crankshaft of the internal combustion engine of a motor vehicle and which contributes to a primary mass, a second sheet metal part which is mounted rotatably about the axis of rotation relative to the primary side first sheet metal part and which forms a secondary mass contributes, and a torsion damper device which connects the primary-side first sheet-metal part and the secondary-side second sheet-metal part in a torsionally elastic manner. Additional masses for increasing the primary mass are arranged at special locations.
- the secondary mass is not formed solely in the actual dual-mass flywheel assembly, but components of an adjacent assembly, which are fixedly connected to the secondary side of the dual-mass flywheel, are also used to increase the latter.
- the neighboring assembly is a dry clutch and its engine-side components can increase the secondary mass.
- the invention is therefore based on the object of designing and developing the dual-mass flywheel in such a way that the disadvantages described above are avoided and an increased secondary mass is realized.
- connection of the additional secondary mass in the form of a mass ring with a large diameter over a sheet - led to a smaller diameter - directly to the second sheet metal part on the secondary side has the advantage that the large moment of inertia lies in front of the toothing and this relieves the load.
- the secondary mass can also be increased in critical axial installation spaces.
- Fig. 1 schematically shows a partial axial longitudinal section through a dual mass flywheel 10 according to the present invention.
- Fig. 1 is an axial longitudinal section through the upper half of a dual mass flywheel 10 centrally to an axis of rotation 12 of an indicated crankshaft 14 of the Internal combustion engine of a motor vehicle shown.
- a primary molded sheet metal part 16 of the dual-mass flywheel 10 is attached to the crankshaft 14 and contributes to a primary mass 18.
- Dual-mass flywheel 10 is mounted rotatably about the axis of rotation 12 relative to the primary sheet metal part 16 and contributes to a secondary mass 22.
- Torsion damper device 24 connects the primary-side first sheet metal part 16 and the secondary-side second sheet metal part 20 in a torsionally elastic manner.
- An additional secondary mass 26 is connected in the form of a mass ring 28 with a large diameter via a sheet 30 to a smaller diameter directly to the secondary sheet metal part 20.
- the secondary sheet metal part 20 is connected via a drive plate 32 to an outer plate carrier 34 of a clutch. This connection has two toothings 36, 38.
- the sheet metal 30 and the drive plate 32 extend on different sides of a gear cover 40 of an indicated gear 42.
- connection of the additional secondary mass 26 in the form of a mass ring 28 with a large diameter via a sheet 30 to a smaller diameter led directly to the secondary sheet metal part 20 has the advantage that the large moment of inertia lies in front of the teeth 36, 38 and thus relieves them become.
- the secondary mass can also be increased in critical axial installation spaces.
- the sheet metal 30 is preferably connected to the secondary sheet metal part 20 by a rivet connection.
- the sheet metal 30 can be connected to the secondary sheet metal part 20 by a screw connection.
- Other types of fastening such as soldering, gluing, welding or clinching are also conceivable.
- the sheet 30 and the secondary sheet metal part 20 are formed in one piece.
